Michael J. Fox was in Family Ties with Justine Bateman. Justine's brother, Jason, was Michael's replacement for Teen Wolf.

Oh, yeah, I've thought about that before! It does make a very interesting connection. Justine's real life brother and Justine's TV brother end up playing cousins in the two Teen Wolf movies. I wonder if Jason is jealous of Michael, though.

Jason Bateman was nicknamed the next Michael J. Fox back in the 80s, even before the 2nd Teen Wolf movie. I think Jason looks more like Michael than his own sister.
